1. Using the Macro Facility to Create HTML, XML and RTF output Rick Langston, SAS Institute Inc.

2. What we can use Macro to do  Can generate any text, not just SAS code, such as...  HTML and XML  RTF for Word documents  Examples for HTML and RTF shown herein  Using the new experimental PROC STREAM

3. Macro is like the cormorant

4. Basic example filename new 'mytest.htm' recfm=v lrecl=32767; %macro make_table(nrows,ncols); %do i=1 %to &nrows; %do j=1 %to &ncols; &j %end; %end; %mend; proc stream outfile=new; begin %make_table(2,3) ;;;;

5. What is produced 1 2 3 1 2 3

6. What is produced 1 2 3 1 2 3

7. /* adding newlines */ %macro make_table(nrows,ncols); &streamdelim newline; %do i=1 %to &nrows; &streamdelim newline; %do j=1 %to &ncols; &streamdelim newline; &j %end; &streamdelim newline; %end; &streamdelim newline; %mend; proc stream outfile=new; begin %make_table(2,3) ;;;;

8. What is produced 1 2 3 1 2 3

9. Using the... tags filename prefmt temp; data _null_; file prefmt; input; put _infile_; cards4; this is some preformatted text that we would like to see before our table ;;;;

10. %macro make_table(nrows,ncols); &streamdelim newline; &streamdelim readfile prefmt; &streamdelim newline; %do i=1 %to &nrows; &streamdelim newline; %do j=1 %to &ncols; &streamdelim newline; &j %end; &streamdelim newline; %end; &streamdelim newline; %mend;

11. What is produced this is some preformatted text that we would like to see before our table 1 2 3 1 2 3

12. /* using & and % */ %macro make_table(nrows,ncols); Using row %nrstr(&) col of &nrows %nrstr(&) &ncols &streamdelim newline; Use this link to find out more. %do i=1 %to &nrows; %do j=1 %to &ncols; &j %end; %end; %mend;

13. /* using & and % */ %macro make_table(nrows,ncols); Using row %nrstr(&) col of &nrows %nrstr(&) &ncols &streamdelim newline; Use this link to find out more. %do i=1 %to &nrows; %do j=1 %to &ncols; &j %end; %end; %mend;

14. /* using & and % */ %macro make_table(nrows,ncols); Using row %nrstr(&) col of &nrows %nrstr(&) &ncols &streamdelim newline; Use this link to find out more. %do i=1 %to &nrows; %do j=1 %to &ncols; &j %end; %end; %mend;

15. A tip for handling input HTML  File my.htm contains < 1 & 2 >  We try the following: proc stream outfile=out; begin &streamdelim; %include 'my.htm'; ;;;;  We get noise such as: WARNING: Apparent symbolic reference LT not resolved.

16. A tip for handling input HTML proc stream outfile=out; begin &streamdelim; %let amp=P %let lt=L %let gt=n %include 'my.htm'; ;;;;

17. Using/Creating RTF files  These are script and text based files  Alternate creation from Word  Can’t do this with DOC/DOCX because it’s binary  This example courtesy of Don Henderson

19. What’s in the RTF file?

20. One way to make our RTF file filename classrtf 'class.rtf' recfm=v lrecl=32767; filename new 'new.rtf' recfm=v lrecl=32767; proc stream outfile=new quoting=both asis; begin %let name=Alfred; %let height=69; %let weight=112.5; %let sex=male; %let age=14; &streamdelim; %include classrtf; ;;;;

22. Example macro for alternate method %macro each_student(obsnum); %global name height weight sex age; data _null_; set sashelp.class(firstobs=&obsnum obs=&obsnum); call symputx('name',name); call symputx('height',height); call symputx('weight',weight); call symputx('sex',put(sex,$sex.)); call symputx('age',age); run; filename new "&name..rtf" recfm=v lrecl=32767; filename classrtf 'class.rtf' recfm=v lrecl=32767; proc stream outfile=new quoting=both asis; begin &streamdelim; %include classrtf; ;;;; %mend;

23. Invoking the macro data _null_; set sashelp.class(obs=3); rc = dosubl( cats('%each_student(', _n_, ');' ) ); run;  Use DOSUBL instead of CALL EXECUTE  Creates Alfred.rtf, Alice.rtf, Barbara.rtf

24. Use of DOSUBL %macro getcount(data); %global numobs; Proc sql; select count(*) into:numobs from &data; quit; %mend; data temp; do x=1 to 10; output; end; run;  Code in red is generated by the macro

25. Use of DOSUBL filename outfile temp; proc stream outfile=outfile; begin some text here %getcount(work.temp) obs count for work.temp is &numobs. %let x=%sysfunc(dosubl(%nrstr(%getcount(work.temp)))); obs count for work.temp is &numobs. text after the dosub call ;;;; data _null_; infile outfile; input; put _infile_; run;

26. Use of DOSUBL some text here Proc sql; select count(*) into:numobs from work.temp; quit; obs count for work.temp is. obs count for work.temp is 10. text after the dosub call

27. Summary  Any scripting language is possible  HTML, RTF given as examples  Deal with & and % via %nrstr if needed  PROC STREAM available as experimental in 9.3  readfile to read a file with no tokenizing (9.3m2)
